How Do Air Source Heat Pumps Work?

Extracting Heat from the Air

During winter, air source heat pumps absorb heat from the outdoor air, even when temperatures drop below freezing. This heat energy is then compressed and transferred indoors, where it's used to warm your living spaces.

Leveraging Refrigerant for Heat Exchange

Key to the operation of air source heat pumps is the refrigerant cycle. This cycle involves the compression and expansion of refrigerant, facilitating the transfer of heat between the indoor and outdoor units.

Defrosting Mechanisms for Cold Weather Performance

In cold climates, frost buildup on the outdoor unit can hinder the heat pump's efficiency. To combat this, modern systems are equipped with defrosting mechanisms that periodically melt accumulated frost, ensuring optimal performance even in freezing conditions.

Supplemental Heating Options for Extreme Cold

In extremely cold climates, air source heat pumps may rely on supplemental heating sources, such as electric resistance coils, to maintain comfortable indoor temperatures. These backup systems kick in when outdoor temperatures plummet, ensuring consistent warmth indoors.
